Radiation Emissions of Popular Smartphones

Smartphones have become an integral part of our everyday lives. From work and school to daily tasks, these handheld devices have brought everything into the palm of our hands.

Most people spend 5-6 hours on their phones each day. And, given that our phones emit a tiny amount of radiation, we’re exposing ourselves to radiation for hours each day.

But different phones emit different amounts of radiation.

With the help of data collected by the German Federal Office of Radiation Protection, we visualize the radiation emissions of some popular smartphones in the market today.

Radiation and SAR Values of Smartphones

Smartphones and other mobile devices emit tiny amounts of radiofrequency (RF) radiation. Humans can absorb this radiation when the smartphone is being used or is lying dormant anywhere near their bodies.

The parameter used to measure phone radiation emissions is the Specific Absorption Rate (SAR). It is the unit of measurement that represents the quantity of electromagnetic energy absorbed by the body when using a mobile device.

The Council of the European Union has set radiation standards for cell phones at 2 watts per kilogram, measured over the 10 grams of tissue that is absorbing the most signal.

SAR values are calculated at the ear (speaking on the phone) and at the body (kept in your pocket). For the purposes of this article, we’ve used the former calculations.

Smartphones With the Highest Levels of Radiation Emissions

The Motorola Edge has the highest radiation emission with a SAR value of 1.79 watts of radiation per kilogram. That’s significantly higher than most other smartphone models in the market today and close to the limits set by the EU for cellphones.

Coming in second is the Axon 11 5G by ZTE with 1.59, followed by the OnePlus 6T at a close third with 1.55 W/kg. The Sony Experia AX2 Plus with 1.41 and the Google Pixel 3 XL and 3A XL at 1.39 round out the top five.

Here is a look at the 10 smartphones that emit the highest level of radiation:

Smartphones with the lowest level of radiation

Now that we have detailed the worst offenders let’s look at the smartphones with the lowest levels of radiation emissions.

Smartphones With the Lowest Levels of Radiation Emissions

The smartphone with the lowest SAR value is the ZTE Blade V10, with 0.13 watts of radiation per kilogram.

Mobile devices by Samsung carry some of the least radiation risks. The company has four phones considered to be the best in the category. The Galaxy Note 10+ is the best model in their line-up, emitting a meager 0.19 watts per kilogram.

Here is a look at the 10 smartphones that emit the lowest levels of radiation:

There is currently no significant research proving the harmful effects of phone radiation.

Despite this, people who are in contact with their devices for extended periods can at least quantify their radiation exposure and make choices about which brands serve their needs.

Ranked: The Top 50 Most Visited Websites in the World

In this visualization, we rank the top 50 websites that receive the most internet traffic, from Google to CNN.

Ranked: The Top 50 Most Visited Websites in the World

Estimates vary, but there are upwards of two billion websites in existence in 2023.

If we were to rank all of these websites according to their traffic numbers, we would see a classic power law distribution. At the low end, the vast majority of these websites would be inactive, receiving little to no traffic. On the upper end of the ranking though, a handful of websites receive the lion’s share of internet traffic.

This visualization, using data from SimilarWeb, takes a look at the 50 websites that currently sit at the top of the ranking.

Which Websites Get the Most Traffic?

Topping the list of most-visited websites in the world is, of course, Google. With over 3.5 billion searches per day, Google has cemented its position as the go-to source for information on the internet. But Google’s dominance doesn’t stop there. The company also owns YouTube, the second-most popular website in the world. Together, Google and YouTube have more traffic than the next 48 websites combined.

The power of YouTube, in particular, is sometimes not fully understood. The video platform is the second largest search engine in the world after Google. As well, YouTube has the second highest duration-of-visit numbers in this top 50 ranking. (First place goes to the Chinese video sharing website, Bilibili.)

But Google and YouTube aren’t the only big players on the internet. Other websites in the top 50 ranking include social media giants Facebook, Instagram, and TikTok. In particular, TikTok has seen a surge in popularity in recent years and is now one of the most popular social media platforms in the world.

The Geography of the 50 Most-Visited Websites

The United States is still home base for many of the world’s biggest websites, taking up 30 spots on this ranking. Of these 30 websites, half are operated by Big Tech companies such as Microsoft, Amazon, Alphabet, Meta, and Netflix.

Russia, China, Japan, and South Korea round out the top five.

Top 50 Websites by country

Things get interesting in the “other” category, which includes six websites. Two spots are taken up by Aaj Tak and Globo, which are large media publications in India and Brazil, respectively.

The remaining four websites—XVideos, PornHub, XHamster, and XNXX—specialize in adult content, and are located in a variety of countries. These are often referred to as “tube sites” since they are built on the YouTube model.

Realsrv, the only adult-oriented site in the top 50 located in the U.S., is interesting to delve into as well, since it’s far from a household name. The website essentially supports advertising efforts by redirecting users away from the content they were viewing over to another page (generally premium adult content). This is one of the key ways that adult websites earn revenue.

Where does this data come from?

Source: SimilarWeb

Notes: Websites listed include “all meaningful subdomains”, and categories in the graphic follow SimilarWeb’s categorization system. This is the third version of this graphic. As with previous versions, we aim to use data from November for the sake of consistency and to avoid seasonal fluctuations in traffic. One important detail to point out is that website traffic does not include app traffic, which is why popular platforms like WeChat don’t appear in this ranking.
